How to use tobramycin solution:

Use tobramycin solution as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • An extra patient leaflet is available with tobramycin solution. Talk to your pharmacist if you have questions about this information. Read it carefully for instructions on how to prepare tobramycin solution for inhalation, administer it, clean and disinfect your nebulizer, and care for your Pulmo-Aide Compressor. Talk to your pharmacist if you have questions about this information.
  • If you are also using dornase alfa, do not mix tobramycin solution in the same nebulizer as the dornase alfa.
  • If you are taking several inhaled medicines, talk to your doctor about the best order for taking your medicines.
  • Tobramycin solution is normally slightly yellow in color and may darken with age if it has been left out of the refrigerator. This will not change the effectiveness of tobramycin solution.
  • Do not use tobramycin solution if it is cloudy or contains particles, or if it has been stored at room temperature for more than 28 days.
  • Tobramycin solution is usually used in cycles of 28 days on the medicine, followed by 28 days off the medicine. Follow the dosing schedule given to you by your doctor carefully.
  • Use your doses as close to 12 hours apart as possible.
  • If you miss a dose of tobramycin solution, use it as soon as possible. If it is less than 6 hours until your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.

Ask your health care provider any questions you may have about how to use tobramycin solution.

Important safety information:

  • Tobramycin solution only works against bacteria; it does not treat viral infections (eg, the common cold).
  • Drinking extra fluids while you are using tobramycin solution is recommended. Check with your doctor for instructions.
  • If severe diarrhea, stomach pain or cramping, or bloody stools develop during treatment or within several months after treatment with tobramycin solution, check with your doctor or pharmacist right away. Do not treat it without first checking with your doctor.
  • Be sure to use tobramycin solution for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
  • Long-term or repeated use of tobramycin solution may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.
  • Tell your doctor or dentist that you take tobramycin solution before you receive any medical or dental care, emergency care, or surgery.
  • Lab tests, including kidney function, hearing tests, and tobramycin levels, may be performed while you use tobramycin solution. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Tobramycin solution should be used with extreme caution in CHILDREN younger than 6 years old; safety and effectiveness in these children have not been confirmed.
  • PREGNANCY and BREAST-FEEDING: Tobramycin solution has been shown to cause harm to the fetus. If you think you may be pregnant, contact your doctor. You will need to discuss the benefits and risks of using tobramycin solution while you are pregnant. It is not known if tobramycin solution is found in breast milk after inhalation. Do not breast-feed while taking tobramycin solution.
